Water Mist System

What is a water mist system?

A water mist system is a fire protection system which utilises water, high pressure and specialized sprinkler spray heads to form very fine water droplets, ranging from 50 to 300µm depending on the system design.

This increases the overall surface area of the water being deployed and such, much smaller supply quantities of water are required in comparison to a standard sprinkler system.

How Water Mist Suppression Works?

These small, atomized water droplets allow the water mist to suppress fires by:

• Cooling both flames and gases through water evaporation
• Reducing Oxygen levels through water evaporation
• Reduces radiant heat through heat absorption by the water droplets themselves

The effectiveness of a water mist system in fire suppression depends on its spray characteristics, which include the droplet size, distribution, flux density (i.e. electric or magnetic forces) and spray dynamics, in relationship to the fire scenario.

Advantages for Water Mist Suppression?

The use of water mist fire suppression, when compared to the use of gaseous agents and traditional sprinkler systems, has the following advantages:

• Immediate activation
• High efficiency in the suppression of a wide variety of fire types
• Minimised water damage
• Environmentally sound characteristics
• No toxic issues
